SEPTEMBER 2014
CPC was asked by a customer in Mexico to help solve a continual problem of magnetite
build up in two CCI Drag Valves. The valve applications were HRH Bypass to condenser
(18” x 22” Angle Valve) and HP Steam Turbine Bypass (8” x 8” Angle Valve). CPC’s solution
was to upgrade the plugs to install a magnetite strainer in the plugs as can be seen below.
Magnetite Upgrade Solution
The strainer is designed to collect the magnetite in the plug preventing the magnetite
from passing up through the balance holes and getting trapped between the plug and the
guide bushing which would cause stiction to occur. In addition the gap between the plug
and guide bush is modified. With this solution all magnetite is collected inside the plug and
can be removed during regular maintenance.

smooth and successful return to service. The spare parts were supplied by CPC for all the
valves being overhauled pre shutdown.
CPC delivers complete replacement trim sets for CCI Drag Valves to an American power
